TENSION-REGULATING DEVICE FOR LOOM-SHUTTLES.,'

SPECZIICATION forming part of Letters Patent No. 406,135, dated July 2, 1889.

Application filed March 20, 1889.

T0 aZZ whom it may concern Be it known that I, GEORGE GoonLINE, a citizen of the United States, residing at Paterson, Passaic county, State of New Jersey, have invented a new and useful Improvement in Tension-Regulating Devices for Loom-Shuttles, of which the following is a specification, reference being had to the accompanying drawings, forming a part thereof.

My invention relates to loom-shuttles of the class in which devices for preserving a suitable tension on the weft are employed, and has for its object to provide a shuttle with tension-regulating devices more reliable than those now employed; and to this end my invention consists in the construction which will be hereinafter fully described, and pointed out in the claim.

Figure 1. of the drawings is a plan of a shuttle having my invention applied thereto. Fig. 2 is a part plan of the same enlarged. Fig. 3 is a section on line y y of Fig. 2. Fig.

4 is a section on line :1; 0c of Fig. 1; and Fig.

5 shows the tension-arm in elevation.

A represents a shuttle of ordinary construction, having the usual body A, spindle B, drag or friction tuft E, eyes a and b, and

. recess K. In the recess K of the shuttle-body A, and in a suitable position therein, I pivot on a pin C one end of a tension-arm C, as shown. The arm 0, which is provided at one end of the same with an eye 0', is also provided in one edge and near its pivotal point with a recess 0 to accommodate one of the its arms of a spring D,which latter has one of its arms arranged in the recess 0 formed therefor in the tension-arm C, and the other engaged in the body of the shuttle. The spring D is arranged in a slot G, formed therefor in the body of the shuttle at the end of the recess K, and cannot escape therefrom.

Above the eye a, in which the tuft E is arranged, and between said eye and the delivery-eye b, I form a race F by cutting away a portion of the body of the shuttle longitudinally between the recess K and the side of the shuttle and between the said tuft-eye a Serial No. 303,949. (No model.)

and delivery-eye b, Fig. 4. By this construction of the shuttle between the tuft-eye and delivery-eye the eye O' on the free end of the tension-arm 0, when the weft is in tension in the operation of weaving, is drawn directly under the delivery-eye and over the end of the tuft-eye a, while the free end of the arm 0 is permitted to play back and forth in the race F at and near the place of delivery to accommodate itself to the want of the weft for tension, as hereinafter stated.

The weft sis taken from the quill B through the tuft-eye a to and through the eye 0 on tension-arm G, and from the eye 0' the weft is passed up through delivery-eye b, and from thence to the web. Strain on the weft during weaving draws arm C in the direction of the delivery-eye Z) until eye 0 on the arm 0 enters the race F and finds its position directly under the delivery-eye and between said eye and tuft-eye, which movement of the tension-arm O compresses spring D and puts the same in tension. As the weaving proceeds, a slack in the weft occurs from rebound of the shuttle, back action, or otherwise; and whenthis occurs the spring D forces back the arm 0 and takes up the slack in the weft s, after which the eye 0', under the action of the weft s in tension, resumes its posit-ion underthe delivery-eye b in the race F, to play back and forth therein under the influence of the weft and spring to preserve the tension on the weft.

Having described my invention, I claim as new and desire to secure byLetters Patent The combination, -with the shuttle-body having the race F and recess G formed therein, of the eyes a and b, the tuft E in said eye a, the lever 0, having eye 0 in its free end, and having said free end arranged to play in the race F between the eyes a and b, and spring D, part of which enters the recess G, all substantially as described.

GEORGE GOODLINE.
